Fix 'search_opts' unexpected keyword argument error

When executing 'encryption-type-create' command using resource
name, it will use the findall() in base.py, then error will
occur because list() in findall() used 'search_opts' argument
which list() in VolumeEncryptionTypeManager did not have. Some
other command like 'transfer-delete' met same issue.

This patch will add 'search_opts' argument in list() function
in child class to avoid the bug.
